The Goodman 10123535 Manual Reset Limit Switch (Red) is a genuine OEM high-limit safety control for the GMH950703BXAD gas furnace and compatible Goodman 96% AFUE models. The red button identifies this switch's specific trip-temperature calibration, distinguishing it from other reset limits in the same cabinet. It is a normally-closed thermal device that opens on an overtemperature or flame-rollout condition to de-energize the gas valve and protect the heat exchanger.

OEM vs. Generic

Trip point matters. The red 10123535 is set to a different threshold than visually similar switches, so substituting a generic or wrong-color unit can cause repeat lockouts or defeat the safety entirely. The OEM part guarantees the correct set point, terminal spacing, and bracket fit for this exact position.

Installation Difficulty

Easy (2/5). A short two-wire replacement, roughly 15–20 minutes. Disconnect power before servicing, verify the correct switch location, and address the root cause of any trip before resetting.
